This researcph was carried out during 2008/2009 season to develop and evaluate a cotton stalks puller prototype. Primary field experiments were conducted, to gather characteristics of cotton field and stalks and to determine proper values for tilt angle (f) of 20, 45 and 65 degree, rotating speed (S) of 47.14, 31.5 and 18.9 m/s, with soft or rough contact surface throughout this study. Field evaluation was investigated on the effect of machine efficiency. The experimental design was split-split plot design. Field evaluation experiments were conducted at soil moisture contents of 26, 19 and 11 % (d.b.), with soil bulk density of 1.29, 1.17 and 1.12 g/cm3, respectively. Stalks moisture content were 60, 38 and 22 % under the mentioned soil moisture, respectively. Tilt angles of 450 with rotating speed of 18.9 m/s under moisture content of 19 % were appropriate treatments factors of the puller performance. Rough contact surface and stalks moisture content of 38 % showed the best results in all treatments. Overall, these technical parameters and specifications can be used to manufacture this machine with multiunit in case of mechanical planting to increase the machine field capacity.
